The OBJ file（3D model） in the downloaded sample data seems to have issues #20

I downloaded the sample data and loaded the corresponding OBJ file using Blender. However, it seems inconsistent with what is shown in the paper. Below are the original image and the visualization of the OBJ file. It appears that the upper part of the vehicle is not well reconstructed, But the paper shows good results. Could you explain why this might be? Or is there any additional step I need to take to achieve a better 3D model?

Selection_114 image

The image like this: frame_00268

Hi. The obj file is generated by 3Dscanner. In our paper, we use 3DGS to reconstruct 3D models.

thx. I found the pipeline in the Paper image I noticed that the pipeline does not involve the 3D GS part. So, I need to take the provided COLMAP data format and perform 3D GS model reconstruction myself to obtain the final PLY file, correct?

Thank you for your assistance.

Correct.
